The open-concept floor plan remains one of the most requested upgrades for older homes in Pasadena. By knocking down walls between the kitchen, dining, and living rooms, you can drastically increase natural light and modernize the flow of your home. However, taking a sledgehammer to an interior wall without proper structural analysis can cause your second floor or roof to literally cave in.
At Everlasting Construction & Design, we specialize in heavy structural modifications. Before you begin a major interior remodel, you must understand the engineering and permitting requirements behind removing a load-bearing wall.
Identifying a Load-Bearing Wall
A load-bearing wall supports the weight of the structural elements above it—such as the roof truss, the second-story floor joists, or heavy appliances like bathtubs. While a licensed structural engineer must make the final determination, there are a few clues that indicate a wall is structural:
Perpendicular Joist Alignment
If you can see the floor joists in an unfinished basement or attic, look at how they run. Walls that run parallel to the joists are usually non-load-bearing (partition walls). Walls that run perpendicular to the joists are almost always load-bearing.
The Engineering Solution: Beams & Point Loads
When you remove a load-bearing wall, the weight it was holding up must be transferred elsewhere. This is achieved by installing a massive structural header across the new opening. Depending on the span (the width of the removed wall), we use either Laminated Veneer Lumber (LVL) beams or heavy steel I-beams.
This beam cannot just rest on the existing floor. The weight of the entire roof is now concentrated on the two ends of the new beam—these are called "point loads." We must install heavy-duty support posts at these ends and transfer that weight straight down into the earth. Often, this requires cutting into the concrete foundation in the basement or crawlspace and pouring new, reinforced concrete footings.
Designing the Open Concept
Once the massive structural beams are hidden in the ceiling or wrapped in decorative wood, the real fun begins: designing the space. An open floor plan requires careful consideration of flooring transitions, kitchen island placement, and lighting zones to maintain visual separation.

In California, any modification to a load-bearing structure legally requires a building permit, signed off by a licensed structural engineer. Attempting to bypass the city permitting office is a massive risk. Not only can the city force you to halt construction and tear down unpermitted work, but unpermitted structural changes can void your homeowner's insurance policy and prevent you from selling the house in the future.
As your general contractor, Everlasting Construction & Design handles the entire bureaucratic process. We work directly with top-tier structural engineers to draft the blueprints, submit them to the Pasadena building department, and manage all rough and final city inspections.
